Dear Gromacs users,
I just compiled gromacs 5.0 with the same compiler (gcc 4.7.2), same OS
(RHEL 6) same configuration options and basically everything than my
previous gromacs 4.6.5 compilation and when doing one of our typical
simulations, I get worst performance.
4.6.5 does 45 ns/day
5.0 does 35 ns/day
Do you have any idea of what could be happening ?
